Field Validator that checks if the short specified is within a certain range.

fieldName - The field name this validator is validating. Required if using Plain-Validator Syntax otherwise not required

min - the minimum value (if none is specified, it will not be checked)

max - the maximum value (if none is specified, it will not be checked)

parse - if set to true, minExpression and maxExpression will be evaluated to find min/max

minExpression - expression to calculate the minimum value (if none is specified, it will not be checked)

maxExpression - expression to calculate the maximum value (if none is specified, it will not be checked)

You can either use the min / max value or minExpression / maxExpression (when parse is set to true) -
using expression can be slightly slower, see the example below.
Do not use ${minExpression} and ${maxExpression} as an expression as this will turn into infinitive loop!
